Problems solved by technology

[0004] At present, in domestic and foreign research, path planning is mainly based on the optimal path planning based on traffic information according to user needs. The criteria for the optimal path include: the lowest cost, road section avoidance, and passing through specific areas. The navigation process from the start point to the end point at the cost of the lowest cost, distance, time or cost, does not cover the health needs; in terms of dealing with air pollution, it is mainly the people who wear masks spontaneously or go out less when the PM2.5 value exceeds the table. coping behavior

Embodiment Construction

[0062] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0063] as attached figure 1 As shown, the route planning device based on PM2.5 healthy travel in the present invention obtains the PM2.5 concentration value through the vehicle-mounted PM2.5 detection equipment and establishes a traffic database in combination with traffic flow parameters. When the user enters the starting and ending information for navigation, the traffic data is imported into the GIS database, and the improved Dijkstra algorithm is used for line matching, and the matched line is transmitted to the web server through the cloud, and finally displayed on the user terminal computer or mobile phone .

[0064] as attached figure 2 As shown, the path planning method based on PM2.5 healthy travel in the present invention is an improved Dijkstra algorithm. After the user inputs the start and end points, the network topology map is loaded...

Abstract

The invention discloses an apparatus and method for route planning based on a PM2.5 healthy trip. The apparatus comprises three parts of a vehicle-mounted PM2.5 detector, an information transmission module, and a server terminal, wherein the information transmission module includes a GPS module and a GPRS module; the server terminal includes a route planning module; and the PM2.5 detector is mounted on a floating vehicle and is connected to the information transmission module, which is connected to the server terminal. A mobile device of a user can easily access data in the server terminal by means of a browser. According to the method, an improved Dijkstra algorithm is adopted, an integrated PM2.5 concentration is mainly taken as impedance, and a minimum total concentration is taken as a target. A healthy trip is planned according to an optimized function taking a PM2.5 optimal route as the target.

Description

technical field [0001] The invention belongs to a route planning and navigation system based on big data, and in particular is a device and method capable of detecting PM2.5 value and realizing healthy travel route planning. Background technique [0002] With the gradual improvement of the road network, the number of cars is increasing, and the high-density urbanization process has made the traffic situation increasingly tense and the air pollution is becoming more and more serious. Due to the complex composition of atmospheric particulate matter, the heavy metal elements and cyclohydrocarbon organic substances carried by it enter the human body along the respiratory tract, seriously endangering human health. Among them, PM2.5 is the most harmful. Its particle size is small and its specific surface area is large, so it is easier to accumulate toxic substances. According to research, PM2.5 pollution is positively correlated with the disease rate of adult respiratory system. ...
